            SPECIAL REPORT: EVs
           Pushing the Limits of Weight and Power Delivery

           in EV Hypercars

           strategy, I didn’t imagine that a few weeks
           later, I’d be out at a show for supercars and
           hypercars, talking to car designers about
           electric vehicle and hybrid vehicle strategies
           and design challenges.
             When I was asked to cover the Goodwood
           Festival of Speed, I was concerned there
           might not be much to cover for EE Times at
           this motorsports event. I’d never been to the
           show before, but I knew that for most of the
           160,000 car enthusiasts who attend, the four-
           day event is all about performance and speed.
